Abstract
A foamed body that is a porous foamed body including inorganic fibers other than asbestos, and having a compressive stress when compressed at normal temperature at a compression ratio of 80% of 0.1 MPa or less and a recovery ratio when compressed at normal temperature at a compression ratio of 80% of 50% or more.
Claims13
A foamed body that is a porous foamed body comprising inorganic fibers other than asbestos and having:
- (i) a compressive stress of 0.1 MPa or less when the foamed body is compressed at normal temperature at a compression ratio of 80% and (ii) a recovery ratio of 50% or more when the foamed body is compressed at normal temperature at a compression ratio of 80%,
- wherein:
- the foamed body is an inorganic fibrous foamed body, and
- the foamed body is obtained by treating either a dried foamed body or a fired foamed body with a silane coupling agent or a titanium coupling agent.
